IMPROVEMENT IIII PLOWATTACHM ENTS.

Specification forming part of Letters Patent No. 184,621), datedNovember 21, 167i; application filed September 30, 1876.

To all whom it may concern:

Be it known that I, GEORGE S. KING, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented a new and valuableImprovement in Attachments for Riding-Flows; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure l of the drawings is a representation of a side elevation of myriding-plow attachment, and Fig. 2 is a plan view of the same. Fig. 3 isa detail view thereof.

This invention relates to riding-plows; and it consists in thecombination of adjusting-levers with a gage-wheel for the purpose ofregulating the depth of the plow; also, in the combination of anattaching-plate with said devices, for the purpose of securing them to aplowbeam; also, in the arrangement at the front of a plow-beam of adepth-gage wheel; and, finally, in various subsidiary deviceshereinafter fully set forth.

In the annexed drawings, A designates an attaching plate, provided withan upright standard, A at its forward end, and an upright notchedsegment or segmental rack, A, at its rear end, said standard and segmentbeing made in one piece with said plate. Standard A is provided withslotsa a whereby it is secured to the beam of a riding-plow, and segmentA is similarly slotted at a a for the same purpose. To the outside ofstandard A near the bottom thereof, is pivoted a long lever, B, theshort rear arm of which is expanded, so as to form a toothed segment, B,

that meshes with a similar segment, (3 form ing part of an L-shapedlever, O, pivoted in like manner by its angle to the rear part of plateA. The pivoting in both cases is effected by means of small pivot-bolts,which pass through the said levers into the said plate and standard. Theupper arm 0 of said L- shaped rear lever G is provided with guide loopsor staples c 0, (shown in Fig. 3,) in which slides vertically a lockingrod or dog, D, operated by a handle, (1. When said rod or dog isdepressed it enters one of the notches or grecesses a of the uprightsegmental bar -A standard, (and capable of rotation therein,)

and prevented from falling through the same (when the devices are raisedfrom the ground) by cross-pin g, which is passed through the upper endof rod G, just above the top of said tubular standard E. To the lowerend of said vertical rod G is secured a bit'urcated'block or bracket, H,in which is pivoted a gage-wheel, I. To the rear end of operating-leverU, at the corner thereof-,is secured a rearwardlyextending foot-bar, J,adapted to be depressed by the foot of the driver. Gage-wheel Iregulates the depth of the plow, and is raised or lowered, as desired,by rocking-lever (J, forward or backward. Foot-bar J enables the driversfoot and hand to be both employed at the same time. for the purpose offorcing the said gage-wheel hard down upon the surface of the ground, inorder to raise the plow-point by the leverage thus obtained. The saidforward lever is braced by a reach or brace, K, extending from the axleof the vehicle thereto.

Instead of the segmental gears on levers B and 0, links or othermechanical equivalents may be used. Also, any other locking device maybesubstituted for the one shown.

Also, the rod G may be connected directly to lever B, dispensingwithtubular standard E. Various other changes may be made without departingfrom the spirit of my invention.

Kdesignates a reach or brace extending forwardfrom the axle of thevehicle to the said front lever B. Said reach or brace is provided atits rear end with a slot or cleft, K to receive the axle of the vehicle,so that said axle may be adjusted. The said reach is also provided witha plate in front K for attachment to the pivot of the said front leverB, and with a cross piece or foot-rest, Kflfor the drivers feet. Theadvantage of attachin g said reach or brace to said front lever, insteadof attaching it directly to the plow-beam,

is that my arrangement removes the saidreach or brace out ofthewayvoftheworking of said levers B and O. l i What I claim as new, anddesire to secure by Letters Patent, is-- 1. The combinatiomwit'h a'blowbeam, of

attaching-plate A with segmental geared .le-.

2. In a plow, the combination of fixed standard A with pivoted standardE, connectingrod F, plate A, and lever B, substantially as set forth.
